Key Concepts and Formulas You Need to Know

Alright, let's dive into some of the key concepts and formulas that are crucial for success in Technische Mechanik 2. This isn't an exhaustive list, but it covers some of the most important topics you'll encounter.

  • Stress: A measure of the internal forces acting within a deformable body. Normal stress (σ) is force per unit area perpendicular to the surface, while shear stress (Ï„) is force per unit area parallel to the surface.

    • σ = F/A (Normal Stress)
    • Ï„ = V/A (Shear Stress)

  • Strain: A measure of the deformation of a material. Normal strain (ε) is the change in length divided by the original length, while shear strain (γ) is the change in angle.

    • ε = ΔL/L (Normal Strain)
    • γ = Δx/L (Shear Strain)

  • Hooke's Law: A linear relationship between stress and strain for elastic materials.

    • σ = Eε (where E is the Young's modulus)
    • Ï„ = Gγ (where G is the shear modulus)

  • Bending Moment (M): A measure of the internal bending forces in a beam.

  • Shear Force (V): A measure of the internal shear forces in a beam.

  • Bending Stress (σ_b): The stress induced in a beam due to bending.

    • σ_b = My/I (where M is the bending moment, y is the distance from the neutral axis, and I is the area moment of inertia)

  • Deflection (δ): The displacement of a beam from its original position due to applied loads.

  • Torsion (T): A twisting force applied to a shaft.

  • Shear Stress due to Torsion (Ï„_t): The stress induced in a shaft due to torsion.

    • Ï„_t = Tr/J (where T is the torque, r is the distance from the center, and J is the polar moment of inertia)

  • Polar Moment of Inertia (J): A measure of a shaft's resistance to torsion.

  • Euler's Buckling Formula: Used to determine the critical load at which a column will buckle.

    • P_cr = (π²EI)/(KL)² (where E is the Young's modulus, I is the area moment of inertia, L is the length of the column, and K is the effective length factor)

Understanding these concepts and formulas is essential for solving problems in TM2. Make sure you practice applying them to various scenarios to solidify your understanding. Don't just memorize the formulas; understand the underlying principles and how they relate to each other.
